Abstract: An over-molding tool is provided for over-molding an over-mold onto a fiber optic cable assembly. The over-molding tool includes first and second mold tool sets. The first mold tool set applies a first portion of the over-mold onto the fiber optic cable assembly. The second mold tool set then applies a second portion of the over-mold onto the fiber optic cable assembly. In preferred embodiments, the first and the second portions of the over-mold fuse to each other. By employing the first and the second mold tool sets, the fiber optic cable assembly can be supported at closer intervals along its length when being over-molded in comparison to a single, longer mold tool set. In addition, a lower capacity injection pump can be used when applying the over-mold in two portions. In other embodiments, additional mold tool sets can be added that sequentially apply additional portions of the over-mold.
